Atamasco lily (Zephyranthes) grows well in gardens with wet soil in spring and winter, and it does fine in any moist, acidic soil. The pure white trumpets bloom around Mother's Day. Foliage persists through early summer, so provide ample sunshine while plants are in active growth. Voles and other garden critters usually don't eat the bulbs.
